eg: i have a photo gallery page and that have all the galleries i created. and this is a custom post. so my fields are title, content and gallery field. what i want to do is in the gallery page i want to show only title and one gallery image. if visitor click that thumbnail it goes to full gallery view page.. actually i can use featured image section to show that but i think it will be confusing my client. so i want to show only one image in that area.
